SAFE.OR VAULT DOOR BOLTING MECHANISM.

Specification of Letters Patent.

Eatented May 29, 1906.

Application filed October 10, 1904:- Serial No. 227,781.

1'0 a, whom it in/(Ly concern:

Be it known that I, ORVEY PRICE, va citizen of the United States, residing in Plainit in such position without the bolts being under constant tendency to retract or creep back to their retracted position.

A further object is the provision of improved bolting mechanism the bolts of which when shot out are by their position effectively blocked against retraction by vibration or concussion. I

A further object is the provision of bolting mechanism in which a number of safeguards against the premature retraction thereof are provided.

The present mechanism is in part an improvement upon that shown and described in the contemporaneously-pending application of Walter Gaston and myself, Serial No. 202,491, now Patent No. 792,072, dated June 13, 1905, and my application Serial No. 209,156, filed May 23, 1904, in which rimdogging bolts are used for locking the bolts in their protracted position substantially similar to that herein shown and described and is also an improvement in part upon the subject-matter of the several patents for bolting mechanism granted to Henry D. Hibbard. In those patents the bolts when protracted have their inner ends in position to engage a boss carried by the door. In practice, however, it was not found desirable to protract the bolts sufficiently far so that they would be in a dead-center position, in

which position the boss would have had superior effectiveness, since when in such posi tion difficulty would have been experienced in starting them back when it was necessary to open the safe. In the present improvement, however, the bolts are thrown not merely to a dead-center position, but beyond their dead-centers, so that. being off their dead-center position they can be easily started, while the boss has even greater eifectiveness in the present organization than in the said patented structures, since the bolts cannot be jarred away from such boss in the direction in which they must move in order to be retracted. It has also been found desirable to relieve the bolts from the tension and strain under which they were placed when tapered endsthereof engaged, during the entire time the door was bolted in its seat, the walls of the bolt-openings in the jamb, for the reason that the bolts in such an organization have a constant tendency to return to their initial position, and thus open the safe, since owing to such tapered formation when the door was subjected to vibration the bolts tend to slip away from the jamb, this having been only prevented by some suitable additional lock or dogging means. In the present instance the construction is such that while the bolts have the same drawing-in function as is present in those patents, yet when the door is firmly seated the bolts are relieved of any appreciable tendency to return to their starting position, while the door, however, remains under tension, and therefore in firm engagement with its seat, so that a metal-to-metal tight joint is obtained and maintained. I

In the drawings accompanying and forming a part of this specification, Figure 1 is a rear view of a door, showing this improved bolting mechanism. Fig.2 is a cross-sectional view thereof, taken in line a a, Fig. 1. Fig. 3 is a diagrammatic view illustrating the positions of a bolt during its protraction. Figs. 4, 5, and 6 also illustrate the different positions of a bolt during the protraction thereof.

Similar characters of reference indicate corresponding parts in the different figures of the drawings.

This improved bolting mechanism may be applied to various forms of safe or vault doors, but is particularly applicable to that form of door comprising a body 2, having a rearwardly-extending flange 3, forming a chamber 4, in which the bolting mechanism may be located, which chamber is closed by a back plate 5, secured to the door in any suitable manner, as by means of bolts, which when the door is made of unmachineable metal may project into soft-metal inserts located in the flange.

The bolting mechanism comprises a series of bolts 6, located to project around the door, which in the present instance is shown as circular, the inner ends of which are pivotally connected to a rocking plate 7, having wormteeth 8, in mesh with a worm-shaft 9, suitably supported in bearings. This shaft carries at one end a bevel-gear lO, fixedly secured thereto, which is in mesh with a bevelgear 11, loosely mounted upon a spindle 12, which projects through the door with its in ner end suitably supported by a removable cap 13, carried by the back plate. For effecting connection between this looselymounted bevel-gear and the spindle so that on the turning of the latter the worm-shaft will be rotated to retract or protract the bolts suitable clutch mechanism is provided comprising a pair of clutch members 14 and 15, one of which, as 14, is formed on or as a part of the loosely-mounted bevel-gear 11, while the other, as 15, is splined to the spindle and is shifted by means of a clutch-shifter 16, which is operatively connected by a lever system 17 with a pair of combination-locks 18 and 19, so that on the operation of either of such locks the clutch-shifter will be operated. Each of the bolts 6 is provided with a beveled or tapered surface 20 adjacent to its end and in the rear thereof with a plane straight face 21, located to project into an opening 22, formed in the jamb of the body. This opening, one for each bolt or in the form of a continuous groove, is made of suflicient depth to accommodate not merely the beveled face of the bolt, but also an appreciable portion of the plane face thereby and has its wall 23 straight or as a plane surface corresponding to the plane surface 21 of the bolt. The advantage of thisconstruction is that as the tapered faces 20 of the bolts engage the walls 23 of opening, Fig. 4, the door is with great power drawn into its seat, and the contiguous outer edge 24 of the door flush with the surface, which is usually termed the grinding surface around the doorway, (see Fig. 5,) and when the bolts are shot completely home the plane faces 21 thereof immediately in the rear of their tapered or beveled faces 20 are brought into engagement with the corresponding plane faced wall 23 of the jamb, (see Fig. 6,) thereby relieving the bolts of any appreciable tendency to retract, since there is no longer an inclined or tapered surface in engagement with the wall of the j amb-opening to slip or creep back under vibration while still holding the door under tension. In some instances the walls of the bolt openings could be tapered, terminating in an inwardly-extending straight surface, while the ends of the bolts could be straight and without any taper.

In the'present organization the bolts are not thrown merely toward their dead-centers but are shifted to and past such deadcenter points, thus preventing the retraction of the bolts except by the proper means, since should such bolts for any reason start to retract it will be apparent that they would continue to move in the direction in which they have been shifted past their dead-center points, which movement, however, would be stopped by the walls 26 of the door, each of which walls 26 forms one of the walls of an opening through which a bolt passes and also stopped by the wall of the bolt-opening in the jamb when an independent opening is provided for each bolt. From this it will be seen that to project the bolts into the jamb they are given a peculiar swinging motion (illustrated in Fig. 3) in which the final seating of each bolt in the j amb takes place only af ter such bolt has passed beyond its dead-center, so that during its outward movement, which takes place from the line a up to the line b, at which point the bolt is in its deadcenter position, as indicated by such line b, whichwould pass through both the axis of the boss and the pivotal axis of the bolt, one corner, cl, of the bolt first engages the jambopening wall and gradually increases such engagement until the entire bolt comes into engagement therewith, at which time the shank, whichis shown as apart ofthat is, integral with-the bolt-head, is thrown past its dead-center, as indicated by the line 0, at which time the opposite corner 6 of the bolt extends sli htly farther into the jamb-opening than the corner cl. From this it will be immediately apparent that in order to retract the bolts at this time by further movement in this direction it would be necessary to force each bolt past the inner corner 2650f the end wall 26, which would be impossible. Aboss 27, preferably integral with the body of the door,is provided for engagement With the inner ends of the bolts to prevent the retraction of the bolts, since in order to be retracted they must return past their dead-center lines, which is only possible by a swinging movement of the bolts, which can only be accomplished by the means provided for that purpose. Thus it will be seen that the bolt mechanism is so constructed and organized that two distinct and independent means prevent their retraction to wit, that construction which eliminates any tendency of the bolts to creep back, and, secondly, that construction which permits the bolts to be shifted past their dead-center points, so that they cannot be retracted by a further inward movement. In addition to the foregoing I also dog the bolts by means that has now been designated as rim-dogging means or bolts, since they act adjacent to the periphery of the door and which comprises a series of rotary bolts 30, projecting into the locking- IIO bolts and moved in and out by means of a gear-ring 31. These rotary bolts have pinions 32 on their ends to mesh with'the gearring. This gear-ring is rotated by a pinion 33, carried by a bevel-gear 34, loosely mounted on the spindle 12 and to which gear movement is imparted by means of the bevel-gear 10, fixed to the worm-shaft 9 and in mesh with the loosely-mounted bevel-gear 11 upon said spindle. From this it will be seen that on the proper setting of either one of the combination-locks the splined clutch member will be shifted into engagement with the loosely-mounted bevel-gear l1 and movement imparted through the gear 10 to the main bolts, and through this gear and the gear 34 to the dogging-bolts, both of which sets of bolts will thus be operated at the same time. The openings in the main bolts for the penetration of the rotary dogging-bolts are of oblong formation, so as not to interfere with the swinging motion of the lockingbolts. After the main bolts have been fully protracted further movement thereof past their dead-center points is a pivotal movement with the dogging-bolts, as it were the pivot-points, so that owing to the position of this oblong opening it is not deemed necessary to have the ends of the dogging-bolts beveled, as heretofore deemed desirable.

For preventing the turning of the gear-ring prematurely a locking device is provided. It is shown comprising a sliding bolt 40, adapted to enter an opening in the gear-ring and is moved in and out of such opening by means of a lever 41, connected with the clutch-levers, so as to be withdrawn simultaneously with the movement of the clutch-shifter, and as the combination-locks which control this clutch-shifter are in turn controlled by timelock mechanism it will be seen that until the running down of such timing mechanism the clutch cannot be manipulated. As both bevelgears carried by the spindle are idle thereon, the turning of such spindle will not, until the clutch members are connected, impart movement either to the bolts or to the gear-ring, which in addition is locked against movement.

From the foregoing it will be seen that safeguards, in addition to the two hereinbefore described, are provided for against iniproper retraction of the boltsto wit, the rim-dogging bolts, the gear-ring locking device, and the combination and time-lock mechanism ordinarily providedall of which are easily and quickly operated when the time mechanism which automatically controls the working of the bolts runs down and the combination-locks are properly manipulated, but which it is believed are impossible of operation other than in a proper manner, so that the retraction of the bolts other than by a force suflicient to blow the entire structure to pieces to the injury of the contents or a long and tedious operation in a machineshop to grind. an opening through the door, which will be of unmachineable metal, is not believed possible.

In conclusion, it is to be understood that the various details may be more or less modified without departing from the scope of my invention and that these improved bolts may be used in connection with any suitable means for operating them and in connection with various forms of safe or vault doors and Whether the bolts project into or at the rear of the jamb with separate openings or as a continuous groove, &c.
